Trends in Unprotected Left Main Percutaneous Coronary Intervention and Clinical Outcomes.

ABSTRACT:

Importance

Unprotected left main percutaneous coronary intervention (LM PCI) is recognized as a reasonable strategy for patients who have coronary artery disease with low anatomic complexity. However, recent trends in its procedural volume, patient characteristics, and procedural techniques and their association with clinical outcomes have not been well described, making it important to confirm the safety of LM PCI in contemporary clinical practice.

Objectives

To examine temporal trends in the use and in-hospital outcomes of unprotected LM PCI in Japan.

Design, setting, and participants

This retrospective cohort study used prospectively collected data from the nationwide, multicenter Japanese Percutaneous Coronary Intervention registry including approximately 1100 PCI
